Yes, I understand the rationale, I am just not buying it 100%. As I
said people are well accustomed to values were "less is more" (prices, taxes,
marathon times, ...) and I am not sure whether catering to the lowest common
denominator is all that superior to teaching folks the relevant numbers...
After all the trade-off is that now if people want to decompose or aggregate
RPM values they need to deal with fractions... However for the responsiveness
draft I fully accept that ship has sailed and "bigger is better" it is ;)
